JERUSALEM – A 22-year-old Palestinian terrorist detonated his bomb belt in a Tel Aviv fast-food restaurant yesterday – but he was the only fatality because some of his explosives failed to ignite, authorities said.

“He blew himself up just one meter from me,” said Yitzhak Sharon, owner of Mayor’s Schwarma restaurant, who escaped with minor injuries. “Yes, God does exist.”

More than 30 Israelis were wounded, only one seriously.

“It’s a miracle the damage was so little,” said Police Commander David Tzur.

Palestinian President Mahmoud Abbas said the attack was aimed at subverting next week’s crucial Palestinian parliamentary elections.

“This is sabotage and aimed at sabotaging the elections, not only the elections, but also the security of Palestinians,” Abbas said.

Islamic Jihad, which claimed responsibility, is boycotting the vote.

Hours after the attack, the group released video of the bomber, Sami Abdel Hafez Antar, who declared on it that he was “offering himself to avenge the blood of martyrs.”

At his family’s Nablus home, his brother, Sameh, 32, was at a loss.

“All I can say is that my brother had everything,” he said. “It seemed he wanted martyrdom, and he got what he wanted.”

Witnesses said the bomber posed as a peddler selling razor blades at about 3:45 p.m. when he entered the open-air stand next to Tel Aviv’s central bus station.
